This manual thermostat provides an amazingly simple way to access the heating and cooling options in your home, without any traces of mercury. Controls are easy to follow and allow users to pinpoint the exact amount of their ideal temperature. This is a standard thermostat for heating and cooling that will need to be manually accessed. The YCT51N1008 is amazing in terms of usability and can be used with central oil heating, electric furnaces and central electric cooling options.
